	1. Chapter 1

**Author's Note:**

> This is insane. Technology is the future.

"When are you gonna tell my little brother you got the hots for him?" Rinne asks Aira, after a dance practice session together.

"I dunno, it's just...I dunno if he feels the same way about me." Aira replies.

"Trust me, he definitely likes you. The way he acts towards you is proof enough."

"Are you sure? He's so good looking and his dancing is on a whole other level compared to mine."

Rinne rolls his eyes. "He isn't the type to notice or care about shit like that, Ai-chan." Rinne calls Aira by his nickname for him.

"I know that! But still..." Aira looks down, frowning a bit.

“If you don’t tell him soon, what’re you gonna do when someone else lays claim on him first?” Rinne teases.Aira's eyes widen.

"Like who?"

"How should I know? There are a lot of fan girls of his who aren't exactly shy."

Rinne looks at Aira, sizing him up. It's not like Aira has anything to worry about, being small and cute as he is. If anything Hiiro's the dumbass who should hurry up and ask Aira out before someone comes and snatches him up, Rinne thinks.

"You really think so?" Aira asks.

Rinne stares. No I don’t, he thinks, feeling kind of greedy. And also just in the mood to be an asshole and have some fun. “Yeah, go for it.”

“Ahh, but how should I confess?” Aira feels his cheeks get hot.

“You can practice on me,” Rinne says.

Aira's eyes grow wide. "R-really?"

"Sure. Whatever you do, don't just blurt it out like you always do with everything else. Guys hate that."

"That can't be true!" Aira exclaims.

"Trust me, it is. Look, just say whatever's on your mind. If he likes you too, he'll accept it."

Rinne notices Aira's still looking worried.

"Okay, how about this…" He puts an arm around Aira and gives him a side hug.

He puts his face close to Aira’s, Aira squeaks at the proximity. Rinne grins, “He’s always touching you and standing real close like this right?”

Aira nods.

“So next time he does this what should you say? Try creating the mood. Pretend I’m Hiiro.”

"I-I don't think I can do that…"

"You have to if you want to confess. Now, try it!"

Hesitantly, Aira looks at him. He swallows hard and whispers, "Hiiro…"

He's so quiet that Rinne can barely hear him.

"Come on Ai-chan, speak up." Rinne laughs.

Aira frowns and flusters, "he doesn't call me ‘Ai-chan', and he wouldn't say that! Try to act more like Hiiro!"

"You're the one who should act more like you, but since you seem to be struggling, I'll help."

Rinne gets on his knees and closes the gap between their faces. Aira's cheeks redden and he lets out a little squeak, quickly covering his mouth with his hand.

"B-but Hiiro wouldn't do that…" Aira protests.

"Yeah, but you still don't know how to react."

Aira frowns and looks away from his face.

"Look at me, look at me."

Aira slowly turns his head towards him.

"Let the words come to you, okay?" He cups Aira's cheek with his hand and leans in slowly.

"Umm, Hiiro..." Aira says shakily, eyes going everywhere as it becomes increasingly harder to look at Rinne who is very close to his face and very, very handsome.

"What is it Aira?" Rinne grins.

"I, um, listen...I like you."

Rinne laughs, "That's what you have to say?"

"But that's what I want to say!"

"Then why'd you hesitate? You're supposed to sound more confident."

"I am confident!"

"Then prove it. Be more confident and cut the shit."

"I'm not good at this!" Aira whines.

"Okay," Rinne fake-sighs, "if you can't say it, then you just gotta get him to confess to you first. Try seducing me."

Aira turns bright red, "What?!"

"You heard me. Seduce me," he grabs the back of Aira's head and leans in close to his ear. "Go on, Ai-chan."

"B-b-but..."

"It's simple. Just do it."

"...Okay," Aira takes a deep breath and starts shaking all over as he exhales.

Aira bites his lip in a way he thinks is maybe supposed to be cute or seductive. Rinne can't believe this dumb virgin, he has no idea how to be sexy, does he? But honestly that in and of itself is working. He really wants to toy with this cute boy.

"Aira, you're really cute," he says, still pretending to act like Hiiro, and places his hand on Aira's thigh.

"I-I'm not cute at all," he says, trying to cover his thighs with Rinne's hand, but he only succeeds in pushing it higher.

"Oh, you're cuter than you think." Rinne licks his lips.

"R-really?" Aira hesitates a bit before looking up at him through long eyelashes.

"Yeah, really. Super cute.” Rinne leans in.

"I can't be...cute," Aira says, looking down and biting his lip.

"Of course you are," he whispers, "and I'm going to make you even cuter." With that, he takes Aira's chin in his hand and closes the final gap between his lips with Aira's.

Sorry Hiiro, Rinne thinks in the back of his mind, but I get first dibs.

Aira immediately pushes Rinne off him, blushing hard.

"What! You...! Y-You kissed me!"

"Well yeah, you were the one who seduced me, Ai-chan." Rinne says it like it should be obvious.

"You were supposed to be pretending to be Hiiro!" Aira exclaims, blushing harder. Rinne stole his first kiss...! And he said he was going to make Aira cuter...!

"You're so cute when you blush, though. Why don't you want me to make you even cuter?"

"Because I'm not cute!" Aira's pretty upset now. "Not for you I mean! Only Hiiro can think I'm cute!

Rinne laughs, "What the hell is that supposed to mean?"

Aira pouts, still bright red, but Rinne leans into him again, pinning Aira with his back to the wall.

"You wanna be my brother's boyfriend so badly, but you should know something."

Rinne looms over him, running his hand up Aira's side, "What's my brothers is also mine. What's Hiiro's is mine. So that means you're mine, too."

"W-what are you saying?" Aira stutters.

"You're cute, so I'm claiming you." With that, he kisses him again and this time, Aira doesn't stop him.

This is wrong, Aira thinks, but then he feels something. Like a slight tingling sensation in the pit of his stomach. It feels...good.

Rinne breaks the kiss and looks into his eyes, "Now do you get it?"

Aira's lips are shiny with saliva and his cheeks are flushed a rosy pink.

"Damn, you're cute," Rinne licks his lips and leans down again. Aira shuts his eyes hard, bracing himself for Rinne's lips to find his once more, anticipating another kiss.

But it never comes.

"Aira! Are you in here?" A voice from down the hall calls, and Aira's eyes shoot open to see Hiiro standing at the end of the hallway. "There you are. We're leaving now."

Aira's face falls and he shoots a glare at the older boy who was kissing him a moment ago.

He shoots a look at Rinne as if to say ‘tell anyone we kissed and you're dead!'

Rinne snorts, cute of Aira to think he could threaten him. Still he backs away, "Go on then, Ai-chan."

"Don't call me that!" Aira almost snarls.

“Yeah, yeah, don’t get your panties in a bunch.”

Aira scowls at him, blushing hard, “ugh, you’re the worst.”

"Admit that you actually kinda like me."

Aira's blush deepens and he looks away.

Hiiro calls for him again, "Hey Aira! Come on, we're leaving now!"

"Coming, Hiiro!" Aira calls back. He turns to leave, but then stops. He looks at Rinne one more time before walking away.

"I'll let you live this time, but remember I'm only nice to you because you’re Hiiro’s brother," Aira says, before turning to leave.

"I know, Ai-chan."

Aira frowns. "Stop calling me that."

With that, Aira walks away.


	2. Chapter 2

**Notes for the Chapter:**

> HAppy New Year!1!1!!1!!

Aira was still thinking about his secret kiss with Rinne from before.

He still didn't know how Hiiro felt about him, but now he has no idea what Rinne's thinking either. He clutched his head in both hands, "Ahh, this is so confusing!"

"What is?" Came an annoying voice from behind. Even without turning around Aira could hear the smirk in Rinne's voice. Great, just the last person he wanted to see.

"Rinne, what do you want?" Aira asked exasperatedly.

"Hmm, let's see...I believe I was invited to a party at your place tonight."

"Oh right," Aira remembered that Hiiro had texted everyone about it earlier. "Yeah it's today, I forgot too..."

"Well, I just came from my unit's practice, and I figured I'd stop by here before I go home."

"Whatever,"

Aira forced himself to look away from Rinne, alarmed to find him more good looking than he remembered.

Rinne laughed. "Want to kill some time before then?"

"Who would want to spend time with you?" Aira frowned, full ears turning pink.

"You for one,"

"I regret that already."

"Hey, don't be like that. I know you secretly like me,"

"I'd rather be alone."

"Aww,"

Aira gave an exaggerated sigh, "Fine, what do you want to do, then? And make it quick, Hiiro will be here soon to give me a ride to the party."

"I'll be fast. Let's go to your room,"

"What?" Aira gave him a disbelieving look. "You know my roommate is rarely here and even if he was I wouldn't be able to have you in there!"

"Oh come on,"

"No!" Aira stood up, as if to leave.

"Fine," Rinne frowned, "Then let's go to the dance studio."

"...For what?"

"You'll see,"

Huffing, Aira threw his hands up in defeat and nodded towards the door.

"Fine, let's go,"

With a triumphant look on his face, he turned and started walking towards the dance studio, Aira trailing behind. They walked in silence until they reached their destination, where Aira unlocked the door with a spare key and opened it.

"So, what'd you want to do?" Aira asked.

Rinne didn't answer. Instead, he lunged at Aira, grabbing his shoulders and pushing him against the wall. Before Aira could react, his face was pushed up against the wall, and something wet and slimy was on his neck. He swallowed his immediate reaction of disgust and flicked his head back as hard as he could. He heard a satisfying squelching noise as his assailant pulled off him, and he took the opportunity to shove him away.

"That's what I wanted to do,"

Aira gave him a disgusted look as he wiped off the back of his neck. His cheeks were bright red.

"What the hell!?”

“Wasn’t it nice of me not to leave a mark?” Rinne smirked.

"You're sick," Aira frowned.

"You can't tell me you didn't like it,"

"I can tell you I didn't, and I'm not doing that with you,"

Rinne pouted. "Fine then, if you like Hiiro so much, why don't you go give him a-"

"Alright that's enough,"

Hiiro had somehow snuck up behind Aira and grabbed him by the shoulders. He gave a glare to Aira, then looked at his brother.

"What the hell are you doing?"

"I was teaching Aira how to fend off an attacker,"

"By molesting him?"

"I wasn't molesting him!"

"He...!" Aira stops himself. That was weird, why did he feel inclined just now to stand up for Rinne? After all the gross things he did?

Aira shook his head a bit and started again.

"He was being a weirdo, as usual. I need to go practice." With that, Aira pushed past Hiiro and went to find a secluded spot in which to sing.

Hiiro looked at his brother, eyebrow cocked.

"You're gross,"

"I was just having a little fun,"

"Fun for you maybe. Don't do it again,"

Rinne simply stuck out his tongue. Hiiro shook his head and walked away.

Aira was definitely weird about that, he thought.

Rinne looked after his brother then turned to look at Aira's retreating form.

"He didn't even resist or anything," he mused. Then he went off to find some new fun to have until it was time to crash his little brother’s party.

Aira was still in a daze as he made his way to a secluded spot.

Why did I stick up for him? He asked himself. It's not like what he did was all that bad.

He had no answer, so he decided to put it out of his mind for now and focus on singing.

"Aira, are you ready to go?"

"Wha! You startled me!" Aira froze. 

Hiiro smiled gently, "I came to pick you up for the party, remember?"

"Oh...yeah. Come in," Aira stepped aside to let Hiiro in and saw him glance at the walls, which were covered in notes.

"You've been busy," he stated more than asked.

"Just trying to get a feel for the songs we'll be performing. You did pick good ones,"

"Oh! Right, right. I'll be there in a minute, just let me finish this last bit..."

Hiiro nodded and walked away.

Aira took a deep breath as he closed his eyes.

Rinne’s kiss on his neck hadn’t been gross. Not at all.

Aira gathered the rest of his things and left the room, catching up to Hiiro.

“Sorry, thanks for waiting. Let’s go to the party now.”

Hiiro looked at Aira and tilted his head.

"You're a little more…relaxed," he noted with a smile. "Did you finish what you needed to do?"

Aira simply nodded. He didn't want to talk about it now that his mind was all over the place.

Later at the party, Aira sat alone by the drink bar. Hiiro was surrounded by people, as usual. Even though they came together, he knew this would happen. He stared into his cup, he couldn't get what happened with Rinne earlier out of his mind. It made him upset that he was even thinking about it! He decided to leave soon. He really wasn't in the mood to be there anymore. Aira stood up and-

"Oh, Shiratori-kun.” A voice greeted Aira. It was his roommate, Eichi.

"Eichi." Aira turned to face him. He looked a little different than he did earlier that day. "Your hair is down."

"Yeah,” Eichi smiled. "So where's Hiiro?"

"Over there, surrounded by people as usual," Aira muttered.

"Wow, he's really popular," Eichi said with a smile.

"Yeah, I suppose so."

Eichi looked at Aira. He could tell something was wrong, but he didn't know what. The two of them walked over to where Hiiro was.

Eichi pushed Aira gently towards Hiiro by the small of his back. Aira flustered, "Wait! We don't have to-! Let's not bother him-!"

But Hiiro's face lit up as soon as he saw Aira.

"Hey Aira!!" He waved him over with a big smile. Aira blushed.

Just then Rinne appeared out of nowhere to throw his arm around Aira's tiny shoulders. "Found you, Ai-chan." He grinned.

Hiiro frowned. He didn't like people touching Aira, even if it was his brother.

"Yeah, you found me ," Aira said, rolling his eyes. "What do you want, Rinne?"

"Nothing~" he said in a singsong voice. "I just saw you over here and wanted to say hi."

Rinne waves his fingers at Hiiro, “Oh, were you and my little brother having a chat?”

Eichi cleared his throat. "We were actually talking about our idea for a live performance next month. Aira, why don't you tell them what you were saying?"

"Huh?" Aira looked up, confused. "Oh! Right! Um…" He tried to think up a lie.

"Tell them about the new outfits!" Eichi prompted.

“Yeah, they’re...gonna be cool!” Aira suggests lamely.

"A live?" Hiiro asks cluelessly, fully believing it.

"Oh yeah?" Rinne smirks, not looking half as convinced.

Just then, Keito puts a hand on Eichi's shoulder, "I've been looking for you. Come with me." He says.

Aira looks at Eichi pleadingly, really not wanting to be left alone with the two brothers whom his affections are currently caught between.

Eichi seems to sense this and ruffles his hair. "Don't worry, I'll be back soon," he promises. Aira looks up at him with large eyes.

"I'll make sure he's safe," Rinne promises. "We won't do anything perverted to him."

Taking Aira's silence as confirmation, Rinne continues, "See? Perfectly safe with us."

Aira nods, but doesn't look completely convinced. "...okay," he says reluctantly.

Hiiro glares at Rinne, not liking the way he hugs the smaller boy so tightly to his side like that. Aira stares between them helplessly as Eichi and Keito disappear off somewhere into another room.

"What are you glaring at me for, little bro?" Rinne says with a sleazy grin.

"You're too close to Aira." Hiiro grates out.

"Oh? I didn't know you cared so much," he says, smirking.

Hiiro looks away, cheeks tinging faintly pink. "I don't," he mutters.

"Then why are you getting jealous?"

Hiiro doesn't respond to that, instead staring straight ahead.

Aira looks panickedly between them. He notices Rinne smells faintly of alcohol as Rinne rubs his cheek against Aira's neck.

"Your skin is so soft, Ai-chan." He coos.

Aira turns bright red and Hiiro clenches his fists. 

"Rinne," he says warningly.

"What? I'm just admiring his cuteness."

"Don't touch him like that."

"Why not? I'm just showing my affection for him, and he's not complaining."

Hiiro grits his teeth. "I'm not going to warn you again, Rinne."

Aira feels like he's going to melt.

"If you don't like it, you better take him from me." He taunts, suddenly pulling Aira by the wrist and dragging him to an empty bedroom.

"What are you-? S-stop!" Aira protests as Rinne throws him onto a bed. Aira covers his face, there's no way Hiiro would come after him, he thinks. Hiiro doesn't like him like that, does he...? This is so embarrassing.

Rinne cackles."You're so cute, Ai-chan~"

"S-stop it!"

"Why would I do that? You're too cute."

Rinne's smirk widens as he leans in closer to the smaller boy.

"At first I just wanted to mess with you, but now I kinda wanna make you mine for real," Rinne breathes against his neck. 

It should feel gross, but it doesn't, and that makes Aira confused.

"But, but I like Hiiro!" Aira exclaims in halfhearted protest.

"But you like me too, don't you?" Rinne grins.

"N-no!"

"Don't lie." He leans in to kiss him, and Aira brings his hands up to push him away.

"Stop it! I'm not yours, I like Hiiro!"

"Do you really?"

"Of course I do!"

Rinne sighs."Are you sure you're not just saying that, Ai-chan?"

"Of course I'm sure!"

"But you can't stop thinking about how much you want me inside of you right now."

"Oh god..."

Hiiro bangs on the door.

"Hiiro!" Aira calls out in surprise.

"Aira! Is it true, do you really like me?" Hiiro calls from behind the door. 

Rinne rolls his eyes. "Just when things were getting good," he mutters under his breath in annoyance.

Hiiro forces open the door. Aira stares at him, pinned underneath Rinne.

"Get off him," Hiiro growls. Rinne does, putting his hands up with a shrug.

Hiiro repeats, "is what you said true, Aira? You really like me...?"

Aira bites his lip. He's scared to admit it. After all, what if Hiiro rejects him or doesn't like him back? Plus he hasn't told him about how he kissed Rinne...

"Aira?"

"Ah...um..." Aira stutters, looking over at him. He looks so nervous, Aira thinks to himself. "I..."

Rinne breaks the tension with a loud cackle. "What about you, little brother? Why don't you tell Ai-chan first, how you feel?"

Aira goes wide eyed and stares at Hiiro. How Hiiro feels...?

Hiiro slowly, almost painfully, reveals in a quiet voice, "I like you too."

"You do!?" Aira exclaims. He looks so happy that Hiiro said that. Hiiro nods his head slowly.

Aira pounces on him, hugging him tightly. "You do! You really do!"

"Good for you guys," Rinne rolls his eyes. "Too bad I already kissed him," he adds.

Hiiro shoots a look at Rinne.

"Aira...is that true?" He finally asks.

"It is..." Aira admits, "it just happened. I didn't know if you liked me, and I was confused."

Even now that his feelings for Hiiro are mutual, he can't deny his attraction to Rinne.

"So that's why you were being so distant," Hiiro murmurs, closing his eyes. "I see..."

"I'm sorry, Hiiro," Aira apologizes, looking down at the floor.

Hiiro sighs. "You like me, I like you, but you kissed my brother."

Hiiro thinks about it for awhile. Imagining Aira being kissed by his brother makes something warm bloom in the pit of his stomach.

"Let me see."

Aira's eyes go wide, "What?!"

Hiiro stares at him, "kiss my brother again, right now, and let me watch."

Aira's eyes go wider, "I can't do that!"

Rinne stares at him. "Are you sure?" He asks.

"I can't kiss you in front of Hiiro! It's embarrassing!"

"He has a point," Hiiro nods in agreement.

"Alright then, I'll do it," Hiiro tells his brother.

Rinne laughs, "are you serious?"

But Hiiro is already coming over towards Rinne. He puts his mouth on his brother's and kisses him hard. Aira squeaks and covers his face with his hands, cheeks burning hot as he peeks at them between his fingers.After several long, heated moments, they part.

"There," Hiiro smiles at Aira. "Now we’ve both kissed my brother, so that's good enough for me."

Aira is too flustered to say anything, so he just nods in dumb confusion.

Rinne laughs, “So all that’s left now is for you two to kiss then,” he points to Hiiro and Aira.

Hiiro turns to Aira, "I guess that's what we'll do then."

Aira freezes, feeling giddy with anticipation. He feels his body stiffen as Hiiro's big hands grab his tiny shoulders and he leans in to capture Aira's mouth with his. Aira can taste the alcohol from Rinne's tongue on Hiiro's lips. He finds himself melting into the kiss, his eyes fluttering shut as he feels Hiiro's tongue press insistently against his lips. He parts them, and begins to passionately explore Hiiro's mouth with his own tongue. It's sloppy and wet, and Aira can feel himself getting hard as he wraps his arms around Hiiro's broad, muscular back.

Hiiro pulls away from the kiss, a trail of saliva drips from Aira's shiny wet lips.

Rinne whistles obnoxiously on the sidelines.

"Oh yeah," Hiiro says breathlessly. "I still haven't seen you and Rinne kiss yet, Aira."

Aira peeks over at Rinne, and sees him smirking from ear to ear. He feels his stomach drop nervously as he looks back at his partner.

"Well," he clears his throat, "I guess we should do it then."

"That's what I've been saying," Hiiro laughs.

Rinne stands, swiftly making his way to Aira and grabs him by the shoulders, yanking him forward and planting a wet kiss on his lips. It startles Aira so much that he pulls away for a moment, but then he feels himself melt into it, kissing back with more passion than he ever has before.He can taste the remnants of the alcohol on Rinne's tongue and lips. It's gross, but exciting at the same time. His heart is beating fast, and he can feel himself going red in the face as he realizes that he's actually enjoying this.

He remembers with a jolt that Hiiro's still in the room. He looks over at Hiiro only to see Hiiro's hard and stroking at the front of his pants. Aira's eyes grow wide, did Hiiro get hard watching Aira and his brother kissing?!

Rinne laughs."Oh, is that how it is?"

Hiiro doesn't answer, instead he just smiles in return.

“Looks like your new boyfriend likes watching us kiss,” Rinne says teasingly to Aira. “Guess we should give him a show.”

Aira flushes bright red and looks at Hiiro, “is that...what you want, Hiiro?”

“If you’re okay with it.” Hiiro says.

"I don't...I mean…" Aira starts to say, and then he feels himself being shoved forward. He falls face first into the bed with his ass in the air. Before he can say or do anything else he feels Hiiro's hands on his hips, pulling at his pants.

When he looks up, Rinne is in front of him, unbuttoning his pants as well.

"How about you show Hiiro how else you can use your cute little mouth?" Rinne taunts. Aira looks over his shoulder back at Hiiro, but Hiiro's eyes are clouded with lust.Aira knows that look. He's seen it many times before. It's the look of a predator. He’s seen this wild look in Hiiro’s eyes before when they perform on stage.

Aira closes his eyes and submits to the situation. Admittedly he is really turned on right now. He doesn't resist as his pants are pulled off, leaving him in just his shirt and underwear. When he feels Hiiro grip his underwear and pull downwards he lifts his hips so they can be stripped off as well.

Meanwhile in front of him, Rinne nudges his cock at Aira’s lips. 

“Part those lips, princess.”

Aira does as he's told, and soon feels Rinne's cock sliding into his mouth. Thankfully, he doesn't push it too far back and allows Aira to breathe easily while sucking on him.

Hiiro, meanwhile, slowly begins pressing a finger to Aira's entrance.He doesn't try to force it in or anything, he just gently presses against it. Aira knows what he's doing though, and he begins to silently will him to just put it in already.

Hiiro laughs softly at Aira's cute, impatient expression and quickly shoves his finger in, hooking it forward in order to hit Aira's prostate.

Aira moans, his tongue sliding against Rinne’s cock.

Rinne smacks his lips in approval.

"Seems like he likes it," Rinne smirks.

Aira whimpers as Hiiro crooks his finger, hitting his prostate from a new angle. Aira's mouth slides further down on Rine's cock.

"Ohh, I think he really likes it," Rinne says.

Hiiro crooks his finger again, hitting the spot perfectly. As he does so, Aira begins to moan loudly around Rinne’s cock, the vibration of which causes him to moan as well.

Aira can’t believe this is happening.

“Aira, you’re so good,” Hiiro praises him, “so cute and so good.”

Aira feels his heart swell from the praise and pushes his ass back eagerly onto Hiiro’s fingers with another moan.

“Damn,” Rinne chokes out breathlessly.

Hiiro begins to fuck Aira's tight hole steadily, crooking his finger against Aira's prostate with every thrust.

Aira feels like he's going to come, and unconsciously reaches down to touch himself. Hiiro stops his hand.

"Not yet," he warns in a low voice Aira barely recognizes that sends a shiver up his spine. 

Meanwhile Rinne's grabbed a hold of Aira's hair and begins fucking his mouth freely.

"This is amazing," he says, "Why haven't we done this before?"

Aira's helpless to respond, his mouth is full and all he can do is moan.

Hiiro begins to fingerfuck Aira harder, and Aira begins to feel like he's going to explode.

"I know you're close.” He whispers.

"Hiiro, please," Aira finally manages to moan, sliding his mouth off Rinne's cock with a wet pop. His mind is far gone and hazy and all he can think about is having Hiiro inside him, filling him up. "I want more than your fingers," he whines, barely recognizing his own voice.

"Wow," Rinne laughs and slides his cock back against Aira's lips.

"You're really insistent about it."

"He is," Hiiro says, pushing his fingers in once more before pulling out, "and he's so cute like this."

Aira shivers and whines around the head of the other boy's cock when he pushes inside him again.

"You're amazing, ngh, Aira," Hiiro gushes praise as he pushes in all the way. Aira whimpers helplessly around Rinne's cock again, the vibrations earning a grunt from Rinne above him.

"You're so cute," he repeats, thrusting in and out of Aira with a steady rhythm.

"Amazing, amazing," he chants, picking up the pace until Aira can feel his fingers trembling.

Hiiro massages and squeezes Aira's cute soft ass cheeks with his hands while he picks up the pace. The harsh movements of his hips cause Aira to jerk forward, choking slightly on Rinne's cock. Rinne let's out a deep groan.

"Aira, baby," Rinne hisses.

"He's not your baby," Hiiro half growls.

"Ah, he's yours, then?"

"He's mine," Hiiro says with finality.

"I see how it is," the other boy laughs.

"Come on, Aira. Come for me."

Hiiro growls at Rinne again.

“Sorry,” he smirks, “I meant for us.”

Hiiro slides his right hand from Aira's ass cheek up to his back and begins to firmly scratch at the base of his tail bone, swirling his fingers in slow circles. Aira whimpers, shaking his head.

"Ah…ah…" he whines as he begins to lose himself to sensation.

Hiiro smirks at him.

"You really are something," Hiiro tells him, thrusting in with more force.

"Me first," Rinne grunts, and spills into Aira's mouth without warning. Aira coughs and gags on it as another hard thrust of Hiiro's cock against his prostate rips a needy moan from his throat.

"Are you alright Aira?” Hiiro asks, shooting Rinne a glare.

Aira gasps, slumping forward onto his forearms. His ass sticks up in the air as Hiiro continues to hold him up by the hips. Rinne’s taste lingers on his tongue as he spits out his spunk onto the mattress.

Rinne cackles and sits back to admire the view, a little breathless and pleasantly spent.

"Aira, are you alright?" Hiiro asks again.

"I..." Aira starts, and then he moans as Hiiro slides his cock back into him.

Hiiro picks up the pace again, thrusting into him with a growl.He leans over Aira's back and bites down on his shoulder as he comes. Aira cries out, shuddering as he spills onto the bed with a groan.

"Ah…haaaaah..."

Hiiro's fingers dig into his hips as he empties himself inside Aira, who whines pathetically as soon as he pulls out of him.

"That was hot," Rinne claps his hands, reminding the two of his presence. Aira is too tired to shoot Rinne a disapproving look. 

Hiiro ignores Rinne and wraps his arms around Aira.   
  
"Come on. Let's get you cleaned up," Hiiro says as he helps Aira stand.

"Yes please," Aira sighs, resting his head against Hiiro's shoulder.

Hiiro and Aira step into the shower, and soon the room is filled with the sound of running water.

Rinne closes his eyes and stretches out on the bed, listening to the sounds of the two of them enjoying their intimacy in the shower.

Well, things turned out just great for everyone this way, didn’t they?

**Notes for the Chapter:**

> If you don’t delete stuff and constantly nudge the AI to rewrite stuff or feed it more prompts in the right direction, it will just write shit like this:
> 
> Meanwhile Eichi and Keito return to the living room where they'd left Aira and the two brothers previously only find them no longer there.  
> "Huh." Says Eichi.  
> "Do you think they went back to their rooms?" asks Keito.  
> "Probably."  
> "Should we go see them?"  
> "No, it's late. They must be tired after their... practice."  
> "Hmm."  
> Eichi goes to his room with Keito following close behind.  
> "Well, what do you want to do tonight, Kei-tan?"  
> "Whatever you want to do, Eichi-tan."  
> The two of them engage in intimacy.  
> Meanwhile Hiiro and Aira finish up in the shower. They dry off and head over to Aira's room.  
> "I didn't know you could get erections,"Aira says as he changes into pyjamas.  
> "I can't most of the time," Hiiro says, but Aira doesn't seem to hear him as he's already climbing under his covers.  
> Hiiro finishes changing and gets into bed. He wraps his arms around Aira who happily leans back against him.  
> "Goodnight, Hiiro.Thanks for all your help today," he says as he drifts off to sleep.
> 
> The fucking end I guess
